drm/amd/display: Check if PSR enabled when entering MALL
[Description] - When attempting to enter MALL SS when a PSR panel is connected, we have to check that the PSR panel has already entered PSR because the vsync interrupt call is per display index (can be called for the non-PSR panel first) - Also don't override link settings when programming phantom stream (main and phantom pipe share the same link) Reviewed-by: Jun Lei <Jun.Lei@amd.com> Acked-by: Brian Chang <Brian.Chang@amd.com> Signed-off-by: Alvin Lee <Alvin.Lee2@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
